Abstract:
:The relationship between oxygen uptake (Vo2) and delivery (Do2) was examined in 64 patients immediately after cardiopulmonary bypass. In 44 patients with lactate levels below 2.5 mmol/L, Vo2 decreased proportionally when Do2 decreased below 300 ml/min X m2. At a Do2 over this level, Vo2 plateaued at 105 +/- 13 (SD) ml/min X m2. In a contrasting group of 22 patients with blood lactate levels above 2.5 mmol/L, Vo2 changes depended on changes in Do2 both alone and below 300 ml/min X m2.
